LINOTYPE=MACHINE.

SPECIFICATION formingpart of Letters Patent No. 718,781, dated January20, 1903.

. Application filed June 19,1902. Serial No. 112,347. (No model.)

.are provided with mechanism in which there are tubes or channels foraset of matrices representing about ninety characters. It is desirable,especially for bookwork, to provide the machines with a much largernumber of characters.

In my United States Patents Nos. 608,067 and 610,454 I have describedmeans whereby the capacity of a linotype-machine for distributing,storing, and assembling matrices is largely increased. In said patents,however, this increase was effected by duplicating the magazines andproviding means for distributing to a plurality of magazines.

The present invention relates to means for increasing the capacity ofsingle magazines, whereby without increasing their size they are adaptedto hold from thirty to one hundred per cent. more matrices thanheretofore-that is, the number of channels in the magazines, andconsequently the number of different characters represented, may beincreased from thirty to one hundred per cent.

The invention includes certain modifications in the matrices themselvesand in the distributing devices to provide for the distribution of theadditional matrices.

The invention will now be described in connection with the accompanyingdrawings, in whiohv Figure l is a rear view of the upper righthandcorner of the magazine, showing distributing screw and rail. Fig. 2 is asimilar view illustrating the operation of the distributor stop devices.Figs. 3, 4, and 5 are similar cross-sections through the distributer,illustrating its operation. Figs. 6 and 7 show the preferred manner ofmodifying the matrices to adapt them to the distributer. Fig. 8 is asectional View of the preferred form of the invention. Fig. 9 is asimilar view of a modification. Figs. 10, 11, and 12 are details of Fig.9. Fig. 13 is a front view of a keyboard, Fig. 14 is an showing ashift-key device.

edge View showing the manner of operating a double magazine. Fig. 15 isan inside view of part of the magazine. Fig. 16 is a diagram in plan ofthe supplemental distributing-rails.

In linotype -machines as heretofore constructed the upper ends of themagazine-channels have been of uniform width, the plates at theentrances being spaced about a quarter of an inch apart. The teeth orribs on the distributing-rail were likewise arranged to drop a matrix atevery quarter inch, corresponding with the magazine -entrances. I havediscovered that by making the upper ends of the channels of varyingwidths to correspond with the thicknesses of their respective matricesthirty per cent. additional matrices may be included in'a magazine ofthe construction and width now employed, and by modifying the presentmagazine-entrance construction I am enabled to provide double thevariety of matrices now available. In my Patent No. 608,067 I proposedto increase the number of teeth in the matrices from seven to eightpairs, the number of matrices which may be distributed in the standardlinotypemachine being limited by the number of tooth combinations.According to the present invention I largely increase the variety ofmatrices which may be distributed without disturbing the ordinaryseven-tooth combinations. In other words, I provide means for adaptingthe seven-tooth matrices for distribution in magazines containing manymore channels than those now in use.

Referring to Figs. 1 to 7, inclusive, of the drawings, 1 indicates thedistributing-rail; 2, the rear screw; 3 4, the forward screws; 5, thepulley by means of which said screws are driven, and 6 the stop-pins onsaid pulley. The magazine M is provided in its upper rear portion with aplate 7, hinged on pintles 8, projecting from the stationary portion ofthe magazine. A lever 9 is provided with a pin -10, adapted to interceptthe pins 6 when the lever is raised by the spring 11. The pin 10 isnormally held out of the path of the pins 6 by a stop 12, carried by thehinged plate 7, the rear end 13 of lever 9 normally resting on saidstop. The plate 7 is adapted to have a slight longitudinal movement, tofacilitate which it is provided with rollers 14, resting on the pintles8. It is normally held in the position shown in Fig. 1 by a spring 15.When a matrix sticks in one of the magazine-entrances a succeeding,matrix will engage it and move the plate 7 to the left, Figs. 1 and 2,releasing the lever f) and immediately stopping the distributer in amanner well known.

As shown in Figs. 1 and 15, the channelentrances are of differentwidths, each being but slightly wider than the thickness of the matricesfor which itis intended. These channel-entrances are formed by grooves16 in the front plate of the magazine and corresponding grooves 16 inthe rear plate of the maga zine and the hinged plate '7. The cars of thematrices travel in these grooves. In order that the matrices mayimmediately enter and be guided by the grooves, the plate 7 is carriedup beyond the lower ears of the matrices and provided with a transversegroove 17, in which the lower ears travel as the matrices are movedalong the distributing-rail. It will be seen that when a matrix isdropped its upper and lower ears are both immediately engaged with thegroove in the hinged plate and a moment later with the groove in thefront plate. Should a matrix stick in the entrances,tl1edistributing-screws will immediately be stopped, as heretoforeexplained, and the hinged plate may then be moved back, as shown indotted lines in Fig. 8, to permit the operator to dislodge the matrix.

.I accomplish the result formerly attained by adding two teeth to thematrix and two ribs to the distributing-rail by providing asupplementary rail 1, having at intervals teeth 18 and intermediatenotches 19. This rail, as shown in Figs. 1 and 3, is arranged betweenthe forward distributirig-screws, its upper edge being in line with thelower edges of the lugs of the matrices 20 as they travel on the rail 1.

I modify a portion of the matrices, as shown at 21 in Fig. 6, byomitting the lower corners of the upper ears on one side. A matrix soconstructed will drop from any part of the distributing-railthat is, itsdropping will not be interfered with by the teeth or projections of therail 1. A complete matrix 20, such as shown in Fig. 3, can only dropfrom the distributer when it registers with one of the notches 19 in therail 1, as in other positions it would be intercepted by the projections18. By this simple modification of the matrices I am enabled to doublethe number of seven-tooth matrices which may be distributed by a singledistributing-rail. I am also enabled to drop the matrices accurately inthe magazine entrances, which are just large enough to receive them. Inthe above embodiment of the invention two sets of matrices will have thesame tooth combinations, but different characters. One set, 20, will beprovided with the ordinary square upper ears and the other set, 20, willbe provided with recessed ears, as shown in Fig. 6. These two sets ofmatrices will be released from the rail 1 at the same point. At thispoint the matrices 20 will drop into their channels. The matrices 20,however, will travel a short distance farther, resting upon one of theprojections 18, and will be dropped in the adjacent channel tlnough thesucceeding notch 19.

A sin jo rail 1 may be used, the matrices being pre rented from tippingwhile supported on it by resting against the lower screw 4. By using twosupplementary rails 1 1 and cutting away one-third of the matrices onthe left side and another third on the right side, as shown in Figs. 6,7, and 8, I am enabled to distribute three sets of seven-tooth matricesfrom a rail 1, which has the same combination now required to distributeone set. The operation of distributing three sets of matrices will beunderstood from the diagram of the rails 1 1". (Shown in Fig. 16.)Referring to Fig. 16, it will be seen that three matrices having thesame tooth combination will be dropped into the channel-entrances 16, 16and 16, respectively, which are indicated in dotted lines. As thematrices reach the channel 16 they will be released from thedistributing-rail. The matrices belonging to the channel 16, havingtheir rear upper ears cut away, will drop into said channel. The othertwo classes of matrices will be prevented from dropping by reason oftheir rear upper ears resting on the tooth 18 of the rail 1". Of theremaining matrices those having their forward upper ears cut away willbe dropped into the channel 16 while the matrices having neither upperear cut away will be sustained by the tooth 18 of the rail 1 until theyreach the channel 16, into which they will drop. In like manner thereare three sets of matrices for each combination of teeth, one set havingtheir rear upper ears cut away, another set having their forward upperears cut away, and the third set having upper ears of the usualrectangular form.

Figs. 9 to 12, inclusive, show means for distributing simultaneouslyinto two magazines. In this form of the invention there are twomagazines M M arranged one above the other. These magazines have commonpartition-plates 30, separated by a comb 31. The alternate tongues ofthe comb 31are bent forward and guide the matrices into the rearmagazine M while the other tongues 31 of the comb are bent rearward andguide the matrices into the forward magazine M. By this arrangement I amenabled to increase the capacity of the magazine to the utmost limit, asthe partition-plates are thin and the spaces between them may besubstantially equal to the thickness of the matrices. Themagazinechannels proper, however, may be made wide enough to permit offree movement of the matrices and may have substantial ribs betweenthem.

In Fig. 13 I have shown means for operating parts of two sets ofmatrices from a single set of keys. The keys operate a single set ofrods 32, which are shiftable by means of a lever 33 to cause them toregister with either of two sets of rods 34, arranged upon them, thelatter rods being connected with the matrix-delivery pawls. In Fig.14 isshown a keyboard having a single set of rods 32 and a double set of rods34, the latter connected with the escape-pawls of upper and lowermagazines M M While my invention is primarily an improvementinlinotype-machines of that class in which the matrices have V-shapedserrated notches which cooperate with a distributing-rail having aV-section, it will be evident that certain featn res of the inventionare applicable to other forms of typographic machines.

I believe myself to be the first to provide an automaticdistributeradapted to distribute matrices into a magazine havingchannel-entrances of different widths, all distributers heretofore usedhaving been adapted to drop or eject type or matrices at pointsuniformly spaced. In the present invention the channel entrances orthroats are adjacent, being separated only by thin plates of uniformthickness. The matrices are liberated from the distributing-rails whenthey are opposite the center lines of the entrances of their respectivechannels, and these center lines are unequally spaced; hence the unequalspacing of the distributer-rails.

In the form of the invention illustrated advantage has been taken oftheears which ocour on standard linotype-matrices. Certain other matriceshave been proposed having no ears, and in such cases I would providelateral projections to be used in conjunction with the auxiliarydistributer-rails.
